Abstract (en)
[origin: WO9909089A2] Stable aqueous emulsions of epoxy resins are provided using an epoxy-functional surfactant prepared by reacting an amidoamine having formulae (I), (II) and (III), wherein R<1> is an alkyl, aryl, or arylaklyl group or mixtures thereof having 1 to 15 carbon atoms, R<2> is aliphatic, cycloaliphatic, or aromatic group having 2 to 18 carbon atoms optionally containing non-reactive oxygen or at most an average of 4 secondary and/or tertiary nitrogen atoms per structure in the backbone, X and Y are independently a hydrogen, methyl or ethyl group with the provision that if X is methyl or ethyl, Y is hydrogen or if Y is methyl or ethyl, X is hydrogen, and n+m+o is a real number from 40 to 400, and n+o is a real number in an amount effective to provide resin emulsification, and the ratio of (I) to (II) by weight is in the range of 100:0 to 0:100, the ratio of (I) to (III) by weight is in the range of 100:0 to 0:100, and the ratio of (II) to (III) by weight is in the range of 100:0 to 0:100, and at least one epoxy resin having a functionality of from greater than 0.8 epoxide group per molecule in an amine to epoxy equivalent ratio of at least 1:2; a process for the preparation of said aqueous dispersion and epoxy functional composition prepared by reacting the before-mentioned amidoamine with an epoxy resin.
